Question

how can you represent a baby growing 13 inches in a year in integer

Answer 1

y=13x
where x is a number of years,
and y is the total growth.

but it is supposed to be
y=13x + B

where B is the initial height, because initially he is NOT zero inches high ( ? )

Answer 2

y=13x where x are the years

Answer 3

y=13x+b

Answer 4

yeah he cannot be 0

Answer 5

( "b" would just be the vertical shift of the line, as far as the equation goes.) But, they should have given you the initial height, or the b .

Answer 6

yeah

Answer 7

Tessabella, does that make any sense? the equation that was given by the other people?

Answer 8

I wouldn't say that it makes sense. There is not enough information to make this equation make sense.
We are not given the initial height.

The growth itself though can be represented by y=13x.

Answer 9

But it is only asking for a single year, so x wouldn't need to be multiplied by the 13

Answer 10

Looks like that she meant "per year" by saying "in a year" .

Answer 11

Yes, but children don't grow 13 inches each year. I think the question is asking if a baby grew 13 inches in a single year, how would you represent that?

Answer 12

I don't think it is possible that a child grew 13 in a year. Be realisitic. Maybe 7 8 inches, but for sure not 13.

Answer 13

Well it is not realistic for a child to grow exactly 13 inches each year.

Answer 14

13 inches is too much in a single year. Even when a child is growing the most.
Unless he is a giant....

Answer 15

well it is just a problem of course t is not truw

Answer 16

it is a fiction we practice math not medicine
